What Makes Farmers Aware in Adopting Circular Bioeconomy Practices? Evidence from a Greek Rural Region

Action 2 of the European Union’s Updated Bioeconomy Strategy, i.e., “Deploy local bioeconomies rapidly across Europe”, promotes education and training in all member states. It is a fact that Greece has not yet adopted a national bioeconomy strategy, so stakeholders and farmers cannot benefit from its potential. The adoption of bioeconomy practices is now a prerequisite for receiving funding under the Common Agricultural Policy 2023–2027. Farmers unknowingly use some bioeconomy practices on their farms, and in this study, an attempt was made to investigate how farmers in the region of Western Macedonia would like to be trained in respect of the bioeconomy, knowing the opportunities it offers. The research was conducted through a structured questionnaire answered by 412 farmers from the region. The findings from the subsequent k-means cluster analysis show that farmers can be classified into three clusters: engaged, restricted, and partially engaged. The perceptions that predominate in each cluster are influenced by age, income, and the regional unit in which the farmers reside. In addition, the decarbonization of the Western Macedonia region influences their views and how they would like to be informed about opportunities arising from the bioeconomy. Limitations in this study include the fact that the sample consists only of farmers living and operating in a particular region. In addition, there is an urgent need for political will to establish a national strategy for the bioeconomy. The importance of the present study lies in the fact that few studies have addressed the training of farmers on bioeconomy issues either in Greece or internationally.

The Emergence of Non-Energy Uses of Coal and the Future of Lignite Mining in a Region of Low Carbon Footprint, a Case Study

Abstract The rapid development of renewable energy sources, which has been going on for the last two decades, allows now the elimination of the coal use for power generation. Nevertheless, coal will continue to be used in key-industrial sectors, such as steel and cement production, which are crucial for maintaining the living standards of modern society. The future remains doubtful for coals of poor quality characteristics, such as lignite, which is used almost exclusively for power generation purposes. The present study aims to show that, even in the case of lignite, the transition to a zero-carbon economy must be decoupled from the mines closure. In this context, a combined SWOT–AHP analysis was conducted in order to compare seven potential non-energy uses of the lignite produced in the mines of Western Macedonia region, based on six criteria that are in line with the framework set by the European Union for the selection of the best technologies for every site-specific case. This comparison showed that the most promising technologies are related to the production of organic fertilizers and soil amendments, raw materials and products for the construction industry, activated carbon, and graphene. These technologies may contribute to the achievement of socioeconomic and environmental targets that are critical for the just transition of Western Macedonia region to a new, sustainable productive model.

‘What are the goals of kindergarten?’ Consistency of teachers’ and parents’ beliefs about kindergarten goals

The teachers’ perceptions of the curriculum or their beliefs about how children learn can influence the quality of the teaching activity and its final outcome. Furthermore, the importance of an extended cooperation and mutual understanding between the actors involved (kindergarten teachers – parents) seems to be a crucial issue in order to establish a supportive framework. The research is structured in two dimensions. We seek the beliefs of kindergarten teachers (K-teachers) and parents, as well as their mutual perceptions of each other’s beliefs, i.e., K-teachers for parents and parents for K-teachers, about the importance of kindergarten goals. The study was conducted in Greece, specifically in the region of Central Macedonia, in June 2021, after the re-opening of schools due to the Covid-19 pandemic. A sample of 330 K-teachers and 419 parents from public and private schools responded to closed-ended questionnaires, rating –on a 5-point Likert scale- the importance of 14 Kindergarten goals. We found that K-teachers generally underestimated parents’ beliefs about kindergarten goals relative to their own beliefs and overestimated parents’ beliefs about the ‘academic’ curriculum goals; a trend that was not confirmed by the parallel survey of parents’ beliefs. In contrast, parents appeared to express a more balanced perception between their own beliefs and those they perceived K-teachers to hold. We also found evidence of differentiation between private and public schools. According to the findings, a harmonized perception of kindergarten goals by K-teachers and parents in private versus public schools is apparent.

Symbolic Conflict Resolution and Ingroup Favoritism

What are the domestic consequences of symbolic conflict resolution? We isolate the effect of symbolic conflict by looking into a dispute with no material stakes (for one side), but high symbolic ones: the Prespa Agreement, which ended the dispute on the name of FYROM, thenceforth named North Macedonia. Greeks opposed this name because the ancient Macedonian heritage is central to their national identity. Based on social identity theory, we expect this threat to the group’s distinctiveness to increase nationalist sentiment. Using an original dataset of flags displayed in the façade of buildings in Athens and Thessaloniki, which we compare to Lisbon, we find an increase in national flags in the Greek cities after the Agreement. The effect is stronger in Thessaloniki, Greek Macedonia’s capital, where the identity threat was more pronounced. We also find that the treaty shifted voters to the right, especially those residing in the region of Macedonia.

Evaluation of backfat and longissimus dorsi thickness ultrasound measurements as predictors of negative energy balance in pre-partum dairy ewes

Non-esterified fatty acids (NEFA) and β-hydroxybutyric acid (BHBA) concentrations in blood serum are the most used indicators of energy status in dairy sheep. Ultrasound measurement of backfat thickness (BFT) and longissimus dorsi muscle thickness (LDT) is a non-invasive and on-field applicable technique, with no established critical thresholds for assessing energy balance in dairy sheep. The objective of the present study was to evaluate the use of ultrasound indices of BFT and LDT as image biomarkers of negative energy balance in pre-partum dairy ewes. The study was conducted in four commercial dairy sheep flocks in Central Macedonia Region of Greece, that each one reared a specific breed of purebred sheep. The final number of ewes with full records used in statistical analysis was 177 (flock A-Assaf.E, = 49, flock B-Chios = 46, flock C- Lacaune = 42 and flock D-Frizarta = 40). All animal measurements were performed one month (−30 ± 4d) and two weeks (−15 ± 4d) prior to estimated lambing date. Body condition score was assessed by palpation at the lumbar region. BFT and LDT were determined with ultrasonography after body condition scoring, to avoid bias on BCS estimation. The sum of BFT and LDT (TotalT), the LDT: BFT ratio (RatioT) and the difference in BFT (Δ_BFT) and LDT (Δ_LDT) between the two measurements were calculated. Blood sampling of ewes was performed on − 15d for serum BHBA and NEFA measurements. Negative energy balance status was defined as serum BHBA > 0.8 mmol/L or NEFA > 0.3 mmol/L. The receiver operating characteristic (ROC) analysis was used to define thresholds for fat and muscle reserves and mobilization parameters to predict elevated BHBA or NEFA status. All variables with a significant area under the ROC curve were transformed into binary variables and used in 2 multifactorial binary logistic regression models to assess the association of fat and muscle reserves and mobilization parameters with BHBA and NEFA status. Ewes with Δ_BFT > 0.65 mm had 3.2 times (P = 0.002) increased probability to have serum NEFA > 0.3 mmol/L. Moreover, ewes with BFT(−30d) > 6.86 mm, had 6.7 times (P < 0.001) increased probability to have serum NEFA > 0.3 mmol/L. Ewes with a BFT loss had 6.7 times (P < 0.001) increased probability to have serum BHBA > 0.8 mmol/L. Moreover, ewes with TOTAL_T(−15d) ≤ 25.6 mm, had 5.3 times (P < 0.001) increased probability to have serum BHBA > 0.8 mmol/L. The results showed that ultrasound measurements of BFT and LDT the last month of gestation can be used as a reliable alternative to BCS or metabolic profiling for the assessment of energy status in dairy sheep. Measuring BFT one month prior to lambing or TotalT two weeks prior to lambing can both provide reliable estimations.

Combining Artificial Neural Network and Driver–Pressure–State–Impact–Response Approach for Evaluating a Mediterranean Lake

The main objective of this research was to evaluate the surface water system of Lake Vegoritida (Region of Central Macedonia, Greece). The Driver–Pressure–State–Impact–Response (DPSIR) methodological approach was used. The analysis includes data from three (3) stations monitoring point source pollution and recording the most critical water quality measurement parameters in a time series data analysis from 1983 to 1997. The data will contribute to the analysis and was used to investigate, identify, and evaluate possible sources of chemical and ecological changes recorded in the lake. The artificial neural network (ANN) is a valuable tool for making predictions based on the water quality data set. The findings highlighted the increased concentration of nutrients that contribute to the presence of eutrophic conditions, while their seasonal variability is mainly due to factors, such as water level fluctuations and biological processes in the lake. The above, combined with the critical biotic indicators and factors alongside the reduction in biodiversity, indicated that only the most resistant species survive, confirming the previous finding. In Greece, systematic monitoring and reporting programs have recently been implemented, such as the ECOFRAME scheme and the guidelines proposed by the “Intercalibration Group for Mediterranean Lakes”. The water quality status could be classified as “High”, “High to Good”, and “High to Poor”, respectively, while the overall ecological assessment tends to change to poor conditions. The actions required at an early stage concern the planning of programs and actions that contribute to the sustainable management of land uses and the reduction in point sources of pollution, as well as the reduction of the applied quantities of agrochemicals on the cultivated land in the study area.

Optimal Farm Planning and Assessment of Conventional Agricultural Practices under Alternative Scenarios Integrating Life Cycle Analysis

Agricultural production and farm management are inextricable, since managerial aspects for safe and of high-quality food products have led to the development of successful production plans but multifaceted controversies as well. These controversies arise from the focus of policymakers, especially in the EU, to the environmental aspects of agricultural production, creating conflicting objectives for farmers. Energy from biomass derivatives could play a significant role in the dispute for economic and environmental sustainability in agriculture, along with the formulation of agro-energy districts. In this context, an MCDM model was developed integrating LCA data for the assessment of economic, environmental and energy sustainability regarding thirteen major crops in the Region of Central Macedonia in Greece. The model's objectives consist of maximization of farmers' gross income, minimization of emissions coming from farming practices and maximization of energy potentially coming from biomass. Furthermore, three different scenario-based directions allocate different weights to the respective objectives, creating different managerial strategies. The optimal production plan was the scenario in which the weights were allocated by goal programming. The optimal plan proposes the cultivation expansion of energy crops, tree crops, alfalfa and hard wheat to a higher degree. Moreover, a significant reduction to the cultivated areas of tobacco, rice, barley and soft wheat could lead to a potentially viable production plan.

Християнската знат в земите на днешна Република Северна Македония през XV–XVII в.

During the 15th – 17th centuries, in the lands of the present-day Republic of North Macedonia, Christian nobility continued to exist. The Christian spahi, who were quite numerous in the southwest of the Bulgarian lands in the 15th century, gradually disappeared from Ottoman records. In urban centres such as Ohrid and Kratovo, the boyar estate remained. Duce Dimitar Pepić from Kratovo was the most distinguished Christian nobleman in the historical and geographical region of Macedonia in the 16th century, and he was respected by the people as a ruler. We have evidence about many Bulgarian nobles who became ktetors of churches and monasteries, thereby supporting not only the Christian fatee but also their people.

Crisis, innovation and change management: a blind spot for micro-firms?

PurposeThis paper aims to explore how the owners of less competitive micro-firms (MFs) perceive the “crisis–innovation–change management” triangle. It examines whether their understanding of these overarching entrepreneurship theory principles is inadequate compared to the relevant scientific literature.Design/methodology/approachThis qualitative analysis follows principles based on the inductive method and grounded theory, thickly describing the results from research conducted in a sample of 38 tertiary-sector MFs in the Eastern Macedonia and Thrace region – one of the least developed and competitive areas across Europe. It triangulates the data with 11 respective small firms.FindingsMF owners perceive the crisis as an ostensibly exogenous phenomenon, innovation as something quasi-unattainable – although vaguely significant – and change management as a relatively unknown process. This understanding lies somewhat distant from the extant literature that examines the structural nature of crises, the innovational power to exit profound restructurings and the rebalancing requisite for building new overall organizational methods to survive this internal–external transformation. In essence, the triangle crisis–innovation–change management is a blind spot for the examined MF owners as they ignore its significance as an adaptation mechanism – contrary to several direct competitors.Social implicationsBased on the reluctance of these individuals to cultivate their systematic business knowledge, it seems unrealistic that they would seek to pay the necessary high price for business consulting in the future. An ideal solution would be to build public entrepreneurship clinics to provide these less dynamic and adaptable organizations with free preliminary or in-depth counseling. The Institute of Local Development-Innovation could aim to provide free consulting services to reinforce organizational physiology by coordinating different socioeconomic actors.Originality/valueTo the best of our knowledge, this empirical research is one of the first to test the comprehension of weaker MFs – less competitive and developed in organizational terms – to the triangle crisis–innovation–change management.

Pilgrimage and Religious Tourism in Society, in the Wake of the COVID-19 Pandemic: A Paradigmatic Focus on ‘St. Paul’s Route’ in the Central Macedonia Region, Greece

The adverse effects of the COVID-19 pandemic have transformed the worldwide socio-economic environment in various and unpredicted ways. More specifically, the pandemic restrictions and the necessary social distancing have generated questions concerning the ‘day after’ of religious tourism, especially in association with the value attributed to proximity, sharing, and communal worship in the Orthodox Church tradition. For the time being, pilgrimages and religious tourism in the Greek Orthodox context are quite stable and resilient, and seem to be intertwined with cultural heritage, the modern search for authenticity, and the touristic experience. This analysis aims to explore the key factors that may shape the future trends and plans for pilgrimage and religious tourism in the Greek Orthodox segment. For this reason, it will focus paradigmatically on the region of Central Macedonia in Greece, which is known for its religious and cultural heritage. This is an area in Northern Greece, linked to the missionary journeys of Apostle Paul, and to iconic religious destinations, such as mount Athos and UNESCO World Heritage sites like the Byzantine monuments in Thessaloniki. The analysis will further examine the possibilities of developing new and multidimensional forms of tourism, focused on visits to religious sites.

Comparison of Selected Mathematical Programming Models Used for Sustainable Land and Farm Management

The aim of this study is to compare three mathematical programing models used for sustainable land and farm management. The sample for the comparison was 219 agricultural holdings participating as beneficiaries of the measure ‘Modernization of agricultural holdings’ in the Rural Development Plan at the Region of Central Macedonia in Greece. Using the crop plan of the agricultural land of these farms the mathematical programming models calculate the optimum solution under different and conflicting goals. The results of the methodologies of Linear Programming (LP), of Positive Mathematical Programming (PMP) and Weighted Goal Programming (WGP), are compared in terms of the proposed agricultural land changes. The sustainability of farms is measured with the use of eleven economic, social, and environmental indicators. Each model has some unique advantages and disadvantages that can enable it to be implemented in particular situations. In the conclusions to this research the characteristics of each model are highlighted.

Primary education stakeholders’ views on the European Union during the Greek economic crisis

The paper presents Greek primary education stakeholders’ views regarding their quality of life and EU-related issues before and during the euro crisis. The study took place in 2016, and the population was primary education teachers and parents of Eastern Macedonia and Thrace region. Respondents answered sets of questions for two different years: 2009, before austerity measures were applied, and 2016, during the crisis. Responses denote dissatisfaction with their quality of life and the EU in 2016. The findings show significant shifts of views between 2009 and 2016 regarding the institution of the EU, the euro, the relationship of Greece with the EU and European citizenship. 2016 statements reveal increased euroscepticism in teachers and parents’ views and a large proportion of undecided respondents. However, it seems that more respondents adopt a pro-European attitude regarding the common future of Greece and the EU in 2016. All in all, findings show that, in 2016, respondents are divided into pro-European and eurosceptic, which denotes diffuse attitudes towards the European construct and weak identification with European citizenship. Change during crisis can serve as an opportunity for social innovations and education initiatives that will restore trust on the institution of the EU.

Study of Ichthyofauna: Fishes in the Enipeas River's Catchment Area, Central Macedonia, Greece

The management of water resources and the achievement of the Water Framework Directive 2000/60 / EC's objectives were the key research themes for this study. The study of Ichthyofauna was conducted at nine areas of Enipeas river basin in central Macedonia region of Greece. At the sampling stations, the electrofishing method was applied. The physicochemical parameters at the sampling site were measured with a multiparametric HANNA water quality meter, while water samples were collected and transferred to laboratories of the Biology Department of the Aristotle University of Thessaloniki for analysis of nutrients and major ions. Out of nine stations, only one station discovered fish. Because the sampling was only done once, it is suggested that it be repeated at a different time because the research location is located in one of Greece's major catchments. Only three fish species were identified in the entire catchment area, indicating that more detailed studies are needed covering different surrounding areas.

Polyphenols and Minor Constituents in Honey from North Macedonia and Bulgaria

&#x0D; &#x0D; &#x0D; Honey is a highly concentrated sugar solution that is a rich source of many bioactive compounds including numerous minor constituents. Among them, polyphenols such as flavonoids and phenolic acids are the most important classes of pharmacologically active compounds. Together with other minor constituents they are also considered potential chemical markers for the botanical and geographical origin of honey as well as for its authenticity.&#x0D; A solid-phase extraction procedure and HPLC/DAD/MSn method has been applied for identification and quantification of minor constituents in honey from the region of Bulgaria, North Macedonia, and Greece. Solid-phase extraction using Amberlite XAD-2 as an adsorbent was used for sample preparation enabling purification and concentration of the analysed compounds, mainly polyphenols. In total, 16 compounds were identified in the 21 extracts, 3 of them hydroxycinammic acids (caffeic, p-coumaric and ferulic acid), 5 flavonoids (naringenin, chrysin, galangin, pinocembrin and pinobanksin methyl ether) as well as gluconic acid, quinic acid, ascorbic acid, phenyllactic acid, kynurenic acid and abscisic acid in its two isomeric forms. Quantification of the identified polyphenols was made by an external calibration. The results showed that the developed method presented here is suitable for obtaining qualitative and quantitative data for polyphenols of honey.&#x0D; &#x0D; &#x0D;

Young Scholars Conference “Slavic World: Community and Diversity”. Moscow, 24–25 May 2022. Section “Linguistics”

This year, young scientists from Moscow, St. Petersburg, Smolensk, and Regensburg (Germany) took part in the Linguistics section of the conference. The reports were divided into three thematic blocks. The first block was devoted to the connection between the past and the present in modern Slavic languages. The reports touched upon the issues of lexicology, morphology, and syntax of the Russian language in comparison with other Slavic languages, the results of corpus studies of the grammar of modern Slavic languages, and special attention was paid to sociolinguistic research in Slavic national minorities. During the second session of the “Linguistics” section, topical problems of ethnolinguistics were discussed. The vast geography of the research conducted by young scientists involved in the study of traditional culture included the Saratov region of Russia, Serbia, Macedonia, and China. The third thematic block of reports was devoted to studies of printed and handwritten monuments of Slavic writing, as well as texts in modern Slavic languages. Reports were presented in which the glosses in the monuments of the 17th century were analysed, a classification of ancient Russian toponyms was proposed, and the linguistic means of expressing the national idea in a Polish play of the early 20th century were studied. The moderators of the subsections were employees of the Institute of Slavic Studies of the Russian Academy of Sciences, who are experts in each of the designated topics. Scientific communication took place between young scientists, and many presentations were accompanied by lengthy discussions, in which not only the speakers themselves, but also their senior colleagues participated. Some of the speakers take part in the conference every year, while others presented the results of their research within the walls of the Institute for the first time, which indicates the relevance of this conference.

Measuring technical efficiency of Greek red suckler cow breed's farms in Central Macedonia region using a data envelopment analysis model

This study aims to estimate the technical efficiency (TE) of a randomly selected sample of red Greek suckler cow breed farms in the area of Central Macedonia and identify the most technically efficient characteristics of cow-calf operations. Moreover, this work wants to verify the impact of local and European policies in support of the sector on the estimated efficiency. The research investigates the technical efficiency of 64 suckler cow farms by using the data envelopment analysis (DEA) method. Findings reveal that the most efficient farms were larger, with higher gross revenue, and higher cost of fixed capital than non-efficient farms. In addition, the cost of variable capital, which directly affects profitability, was lower on efficient farms. Efficient farms demonstrate better techno-economic results and managerial practices. This is the first research that studies the red suckler cow breed, based on original data obtained from a direct survey in a field interview.

New Serbian records of the slug Tandonia kusceri (H. Wagner, 1931) (Gastropoda: Eupulmonata: Milacidae) suggest its continuous dispersal to the north

Tandonia kusceri (H. Wagner) is a terrestrial slug native to the Balkan Peninsula (S. Serbia, N. Macedonia, Bulgaria and Dobrudja region of Romania) and the European part of Turkey. In Serbia, it was known mostly from the southern regions. The northernmost locality (Palić settlement, near Subotica) reported here suggests that the slug’s distribution is nearly continuous from its native range until Slovakia. The new record was first recognised from the pictures posted on a Facebook group for insect identification in 2021. The identification was subsequently confirmed by anatomical examination. This further emphasises the importance of social media in monitoring the spread of invasive invertebrates.

The Efficiency Score of Small Accommodation Businesses in Non-Coastal Rural Areas in Greece

Small accommodation businesses dominate the rural hospitality industry, producing simple or complex tourist products and services in order to be sustainable and competitive. In this paper, a two-stage data envelopment analysis (DEA) model was applied in a representative sample of 151 small accommodation businesses in non-coastal areas in the region of Central Macedonia in Greece. In the first stage, DEA-bootstrapping is applied to estimate point and interval efficiency ratios of accommodation businesses and identify the benchmark accommodations. The double bootstrapping truncated procedure of Simar and Wilson is implemented in the second stage to investigate the role of five business factors in terms of efficiency. The findings suggest that small accommodation businesses, although they are based in areas where tourist resources abound, are inefficient. Moreover, the results of the truncated regression method showed that the business’s size, the operating days, and the variety of activities (simple/complex) affect business’s inefficiency. On the contrary, the business’s age and their engagement in agriculture or not do not affect business’s efficiency. The results are important for rural entrepreneurs and policy makers, and they will also be useful for the adaptation of businesses to increase their efficiency.

Monitoring of Polycyclic Aromatic Hydrocarbon Levels in Mussels (Mytilus galloprovincialis) from Aquaculture Farms in Central Macedonia Region, Greece, Using Gas Chromatography-Tandem Mass Spectrometry Method.

A new sensitive and selective gas chromatography tandem mass spectrometry (GC-MS/MS) method was developed for the analysis of 26 polycyclic aromatic hydrocarbons (PAHs), including 16 Environmental Protection Agency (EPA) and 15 + 1 European Union (EU) PAHs, in mussel samples from aquaculture farms in Thermaikos and Strymonian Gulf, Central Macedonia Region, in three sampling periods. Concentrations were found at moderate to low values at all sampling sites, without exceeding maximum levels set by EU. Low molecular weight PAHs were predominant in all samples. Seasonal variation of the concentrations was observed; values were slightly higher in the winter period. Use of diagnostic ratios for potential sources of PAHs showed both petrogenic and pyrolitic origin. In comparison to other related studies of mussels from the Mediterranean Sea, Greek mussels cultivated in the studied gulfs are low in contaminants due to minimal environmental pollution effects. Low concentrations of PAHs are in compliance with the low values of other POPs which were found in the mussels.
